Hi Ivanesque,
The MAS edition or the standard edition SD is well suited for hill climbing. I tested it myself on an uphill road and was very satisfied with it. I biked the same road several years ago using a road bike and had a hard time and was even reluctant to use a small folder like the Strida. but the SD’s low gear did help me with the climb (8 km - 10 km)
I have this project of upgrading another SD to 18" wheels and bike the same road this August.
Here are other advantage of having a MAS
- No need to upgrade to alloy pedals
- No need to upgrade to alloy chainwheel
Personally I like the black crank arms , black kick shift plate and the black hubs of the MAS.
